java dead

While I was in a dockerization project in my current job, I got this doubt: Which java can I use?

This doubt is due to :

java download alert

So after some researches I got these conclusions:

(0) Oracle does not show any message related to license changes for java 4,5,6 y 7 downloads. So we can use them, accepting issues and security problems.
(1) Since the java 8 update at April 16, 2019 8u221, all versions and updates for (java 8,9,10,11 y 13) has no cost just for personal use and development purposes. Any other use, needs a Commercial License
(2) Legacy versions prior to 7, does not have and will not have any update. Maybe a sales contact could be a solution if an update in these versions are required for Legacy Systems Support.
(3) If I want to use java 8 oracle version for commercials purposes and FREE, I need to use a previous version of April 16, 2019 8u221 update
(4) An alternative to oracle java 8 version for commercials purposes and FREE are these java open implementations
(5) Oracle Java 9 y 10 has reached end of support.

I will research more about java on heroku.

According to my conclusions:

If your development strictly needs or was developed with JDK 8, you can use Oracle Java SE 8 JDK 8u202 and earlier versions for FREE and commercial purposes accepting issues and security problems.
If You can revamp your development and you want still FREE, and you want to have improvements and security updates, You must use one of these java open implementations?

Until the next,
